2 Claims.

This invention relates to new and useful improvements in carding machines and more particularly to compression rolls therefor.

The principal object of the present invention is to provide compression rolls which in operation compresses the sliver just before the sliver enters the tube leading to the receiving can so that more of the material can be placed in the can than with machines as now constructed and this enables the carding machine to be operated longer than can machines not provided with the invention.

Other objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a top plan view of the rolls and associated apparatus.

Figure 2 is a side elevational view fragmentarily showing the structure represented in Figure 1.

Figure 3 is a top plan view of the rolls in related position.

Figure 4 is a through the rolls.

Figure 5 is an end elevational view of the rolls.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 generally refers to a part of a carding machine at the top of which is the usual coiler head 6, above which is located structure which goes to make up the present invention.

In carrying out the present invention, a feed calender roll 8 is suitably mounted and has a shaft 9 which rotates vertical shaft l through the medium of bevel gears H and I2.

Horizontally disposed and parallel shafts l3 and [4 are mounted over the machine and on uprights l5 and I6. The shafts I3 and M are geared together by gears I! and I8 and as is apparent in Figures 1 and 2, the reduction gearing I9 is provided between the vertical shaft 1 0 and the horizontal shaft l4.

On the shafts I 3 and I4 and located immediately over the coiler head 6 are rolls 20 and 2|. These rolls are suitably secured to the shafts to rotate therewith, the roll 20 having a circumferentially extending and intermediately located groove 22 for receiving a circumferentially extending and intermediately located rib or tongue 23 on the roll 2|.

As will be seen the grooved roll 20 is of greater diameter than the ribbed roller 2| and the groove 22 is of such a size as to receive the sliver so that the entire silver is compressed in the groove by the rib 23. From the rollers 20 and 2| the longitudinal sectional View compressed sliver passes through the usual tube in the coiler and from which tube the sliver is coiled in the receiving can.

By compressing the sliver a greater amount of sliver can be placed in the can than with machines where the sliver is not compressed and this enables the machine to be run longer and places less work on the machine operator and it also eliminates practically half of the creeling of the sliver in the drawing machine.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the claimed as new is:

1. Means for compressing a length of silver formed in a carding machine and just before the sliver enters the coiler of the machine, such of cylindrical rolls located above the coiler and placed in side by side contacting position in a horizontal plane, one roll having a circumferentially extending groove therein intermediate its ends shaped to receive the sliver and the other roller having a circumferentially extending rib thereon intermediate its ends for compressing the sliver in the groove the diameter of said one roll at the base of the groove and the diameter of the other roll at the periphery of the rib being equal and means for rotating the rolls at a uniform speed.

2. Means for compressing a length of sliver formed in a carding machine and just before the sliver enters the coiler of the machine, such means comprising a pair of cylindrical rolls located above the coiler and placed in side by side in a horizontal plane, one

invention, what is circumferentially extending rib thereon intermediate its ends for compressing the sliver in the groove and means for rotating the rolls at a uniform speed, the grooved roll being larger in diameter than the ribbed roll and the diameter of said one roll at the base of the groove and the diameter of the other roll at the periphery of the rib being equal each roll being formed of a single piece of material with the groove on one roll out in the material and the rib on the other roll being formed integrally with such roller.
